From ESS News

Switzerland-based Energy Vault has partnered with US-based Peak Energy to co-develop an AI infrastructure-dedicated, full-stack energy storage plaform based on sodium-ion battery technology.

The companies will develop the platform by pairing Peak Energy’s sodium-ion batteries with Energy Vault’s system design and Vault OS™ software. All systems will be fully integrated into Vault OS™, which will manage the batteries’ performance, optimize dispatch, extend asset life, and maintain Energy Vault’s operational control.

Traditional battery systems are designed for steady grid loads and are not well-suited to the extreme and volatile power demands of AI training and inference. The new partnership seeks to develop a dedicated energy storage architecture tailored for AI Neoclouds – cloud platforms optimized specifically for AI workloads – and AI-first data center operators.

“The rapid growth of AI is exposing fundamental limitations in conventional power infrastructure,” said Marco Terruzzin, Chief Revenue Officer at Energy Vault. “This solution enables faster deployment, lower cost, and improved safety by combining Energy Vault’s integration platform with Peak’s sodium-ion technology.”

The integrated solution will be exclusive to Energy Vault and part of its data center offering. Benefits include simplified electrical design, reduced reliance on traditional UPS systems, lower cooling requirements, and improved handling of high-volatility AI compute loads.
